Definitions

  • the present invention relates to a thin steel strip guide method and apparatus which is wound in a continuous rolling mill to prevent the said steel strip from winding around rollers other than the intended winding mandrel.
  • the invention is particularly suitable for applications where hot rolled steel strip is produced from continuously cast slabs or bars.
  • the typical application of the subject invention becomes necessary, for example, in metal strip rolling mills, when the thickness of the strip is less than 2 mm, and particularly in the case of steel, when the thickness is less than 1.5 mm.
  • Thin hot rolled steel strip is generally made by reducing the thickness of cast slabs in successive stages of rolling until the desired strip thickness is achieved.
  • a winding machine on which the tape is wound up for transport to a bundle.
  • the winding machine comprises a plurality of back-up rollers and at least one pair of pinch rollers which drive the band at the desired speed and tension before being brought into engagement with and wound onto a winding mandrel.
  • the pinch rollers are usually located in a higher position relative to the reel spool, and a series of guide plates force the tape to the mandrel.
  • Prior art winding machines include a pivotally movable flap guide which can change its position to deflect the leading end of the tape toward one of a plurality of winding mandrels in factories equipped to increase the productivity of the multiple mandrel rolling mill ,
  • the high belt speed sometimes causes the front end of the belt to rise in the passageway through the factory's cooling means, and if the leading end of the belt approximates the nip of the pinch roller, it is very likely that the belt will wrap around the belt Pinch roller winds.
  • the invention is therefore particularly useful in winding systems in the production of thin steel strip.
  • the tip of the flap guide which bears against the pinch roller, is made of a material having a very low coefficient of friction.
  • One of the preferred materials for this application is a fiber reinforced composite known as "Micarta” (trademark of Westinghouse Electric Corporation) which finds many uses as a hard, non-abrasive, and machinable material; but other materials can be used for this, as long as they do not lead to significant wear or scoring on the pinch rollers.
  • the Priestley patent discloses a tape winding apparatus for relatively high-speed continuous tape winding, the object of which is to prevent unwanted marks on the tape caused by the build-up of pressure when the winder rolls are at the overlap or at the point of the increased collar diameter hit the band, and the is also intended to provide curved guides and jets of fluid impinging on the front end of the tape to cause the tape to flex as it enters the winding machine towards the peripheral surface of a rotating spool and to be pressed against it.
  • This patent does not provide the solution provided by the present invention to solve the winding problems associated with thin tape, nor does it suggest such a solution.
  • the Johnson patent discloses a device for unwinding and straightening strip material of substantial thickness and for guiding the leading end of the unwound material into a straightening and feeding mechanism.
  • this patent does not disclose the problem of winding thin tape, which is solved by the present invention.
  • the apparatus includes a skirt 34 which is pivotally moved by a hydraulic cylinder but is not used to prevent strip material from wrapping around pinch rollers.
  • the Moser patent discloses a hot-rolled strip winding furnace comprising a tape-receiving guide having an end disposed in a tape-receiving position adjacent the winding drum.
  • this guide is not intended to prevent the belt from worming around pinch rollers or touching said rollers.
  • a two - roller - driving device each with an upper and lower drive roller, which are mounted vertically one above the other, the axis of the upper drive roller in the tape passage direction at the tape entry in the reel behind the axis of the lower drive roller and after detecting the Beginning of the tape through the winding mandrel of the reel is vertically pivotable about the axis of the lower drive roller and behind which a deflection device for the tape is provided.
  • the deflection device consists of a deflection flap, which rests in the vertical position of the drive device on the lower drive roller or the upper drive roller and rests in any other pivot position of the drive device on the upper drive roller. Regardless of the pivoting movement of the propellant device, the deflecting flap is brought into these adjacent positions by means of an air cylinder, which is attached to the frame and acts on the axis of the deflecting flap.
  • An object of the present invention is therefore to provide an improved winding system for use in the production of thin steel strip, for example in Wikkelsystemen in connection with strip hot rolling mills in continuous casting, in which an unnecessary wear of the pinch rollers and / or scoring on the surface of the pinch rollers and / or the band is avoided.
  • a further object of the invention is an improved device for guiding a thin steel strip to the mandrel of a winding machine without disturbing the normal operation and impairing the high speed of movement of the pinch rollers in said winding machine.
  • a winding system according to the invention has several features which allow said winding system to operate reliably and reduce the operating costs of steel mills by reducing downtime and output losses.
  • the objects of the present invention are achieved by the winding system according to claim 1 and the winding method according to claim 9.
  • the first position in which one end of said guide bears against one of said pinch rollers, it is achieved that the thin strip does not rise upwards can wrap around said pinch roller and also be forced to describe a fixed path in the direction of said winding mandrel.
  • the second position in which said guide is not applied to said pinch roller, whereby during the winding operation, after the band has been engaged with the winding mandrel and wound around said winding mandrel, it is achieved that unnecessary wear of the pinch roller or scoring on the surface of the pinch roller is prevented.
  • the winding system according to the invention comprises a plurality of winding mandrels, wherein the guide can be moved to a third position in which said guide allows the belt to describe another path to another winding mandrel while a finished bundle is on another Mandrel is removed, whereby the productivity of the entire winding system is increased.
  • the guide comprises a tip of a non-abrasive, low-friction material such as micarta, so that it does not damage the surface of the pinch roller.
  • the guide is automatically brought to its first position in which it bears against the pinch roller in response to a signal from a first sensor arranged in the upstream mill that a new slab is being rolled and that the front end of the band is approaching the pinch rollers
  • a signal from a second sensor arranged in the downstream winding mandrel that the tape is wound around said mandrel, it is automatically brought to its second position at a distance from the pinch roller.
  • Fig. 1 is a schematic side elevational view of a preferred embodiment of the winding system showing the flap guide in the first position abutting the pinch roller to undesirably adhere the thin steel strip to the pinch roller and winding the thin strip during initiation of the winding operation Steel bands to avoid the pinch roller around.
  • Figure 2 is a similar schematic side elevational view of the winding system of Figure 1 but with the flap guide in its second position spaced from the pinch roller leaving a small gap to prevent unnecessary wear of the guide and pinch roller during operation ongoing winding of the steel strip (while this is wound around the winding mandrel) to avoid.
  • Fig. 3 is a schematic three-dimensional representation of the flap guide and the associated pinch rollers (the upper pinch roller being shown for clarity only).
  • FIG. 4 is a schematic side elevational view of another preferred embodiment of a winding system including two mandrels wherein the first (upstream) of the two illustrated flap guides is shown in a third position and the other (downstream) flap guide is shown in the second position; that the steel strip can run over the first guide and can bypass the first winding mandrel, and wherein the steel strip was taken up by the second flap guide and deflected downwards for winding onto the second winding mandrel.
  • Fig. 5 is a schematic side elevational view of a detail showing an embodiment of the invention for automatic operation of the flap guide.
  • Figures 1, 2, 3, 4 and 5 show various views of the winding system, the same elements being denoted in their structure by the same numbers.
  • Numeral 10 indicates an upper pinch roller which cooperates with a lower pinch roller 12 to advance a thin steel band 14 (e.g., to a winding mandrel 16).
  • the tape runs on a run-down or a cold roller 18.
  • the front end 28 of the tape 14 is pressed by the flap guide 20 down, which abuts the roller 10, so that is prevented that the tape 14 due to the high speed upwards wraps around the pinch roller 10.
  • the portion 22 of the flap guide 20 which bears against the pinch roller 10 is preferably made of a low friction, durable material to prevent wear and scoring on the surface of the roller 10 and is attached to the flap guide 20 by any suitable conventional prior art fasteners attached. Suitable materials for this section 22 are "micarta" -like phenolic or melamine resin textile composites.
  • the flap guide 20 is movable by suitable actuating means 26 about the pivot axis 24, wherein it is at the actuating means 26 z. B. may be a hydraulic or pneumatic cylinder or cam cam roller mechanism, etc.
  • the front end 28 of the belt 14 is forced to describe a path that guides the belt 14 to the mandrel 16.
  • the path of the band to the winding mandrel 16 is determined by suitable guide plates 30 and 32.
  • the flap guide 20 is moved by actuating means 26 to a second position, as shown in Fig. 2, in which Section 22 of said guide is no longer applied to the roller 10.
  • This second position is the normal operating position of the guide during actual winding (to avoid excessive wear of the roller and guide on the one hand and to reduce the force required to drive the upper pinch roller while the tape is being wound up).
  • the winding mandrel 16 is provided with winding rollers 34 which contribute to the formation of a regular spiral collar 36 around the mandrel 16 around.
  • a winding system comprising two successively arranged winding devices.
  • the flap guide 20 is adapted to assume a third position in which it bears snugly against the lower pinch roller 12 (after the cuffing is completed on the mandrel 16 and the cutting of the strap 14 results in a new front end 28 therewith the mandrel 48 can be loaded alternately next).
  • the low-friction tip 22 prevents the new front end 28 from wrapping around the pinch roller 12.
  • the flap guide allows the belt 14 to pass further towards the pinch rollers 38 and 40 while the pinch roller 10 has been raised to allow free passage of the belt 14.
  • the tip 22 will be off the surface the roller 12 is raised and moved back to the released second position.
  • the flap guide 44 functions in the same manner as the flap guide 20 to ensure that the new front end 28 is deflected between the guide plates 64 and 66 and continues to the corresponding second mandrel 48. Thereafter, the flap guide 44 is moved (by the action of the cylinder 68) to the second position (as shown in FIG. 4) as the tape 14 is wound around the mandrel 48 and wound into a collar 50 in conjunction with the winding rolls 60 ,
  • a control for the automatic positioning of the flap guide 20 is shown schematically.
  • the upstream sensor 52 sends a signal 53 to a programmable controller 54 that a front end 28 of the belt 14 moves in the direction of the pinch rollers 10 and 12.
  • the actuator 56 which is controlled by the controller 54, responsive to said signal 53 and causes the hydraulic cylinder 26 to move the guide 20 to its first position, in which it bears against the roller 10.
  • the sensor 58 sends a signal 62 to the controller 54, which then drives the actuator 56 to cause the cylinder 26 to move the flap guide 20 to the second position (thereby eliminating unnecessary movement) long contact of the edge portion 22 of the flap guide 20 with the pinch roller 10 is avoided).
